Specification of Letters'Patent.

rammed Nov. so, 1915.

Original application filed April 23, 1914, Serial No.V 833,625. Divided and this application led October 22,

1914. VSerial No. 868,105.

T0 all whom t may concern.' 1 Y Be it known that I, PETER H. SCHLUETER, a citizen of the United States, and resident of Chicago, county of Cook,`and State of Illinois, have invented certain new and useful Improvements in Kettles, of which the following is a specification and which are illustratedin the accompanying drawings, forming a part thereof.

The invention relates to kettles, and hasV been divided out of my application for patent on cooking vessels filer 'April 22, 1914, Serial No. 833,625.

The object of the invention is to provide a kettle in which large quantities of syrup may be quickly heated orv cooled. TheV invention accordingly contemplates a jacketed tilting kettle having a fluidcoil within its chamber, and provision for circulating a heating or cooling medium simultaneously through both the jacket and the coil.

A detail of the invention provides for a rotation of the coil to further the interchangeability of heat between the jacket and coil and the contents of the kettle.

In the accompanying drawings-Figure 1 is a central sectional view of a kettle embodying the features of improvement provided by the invention; and F ig. 2 is a detail view of the coil with a portion of the coil broken away and the supporting shaftV shown in section.

In carrying out the invention a bowlshaped kettle 10, having a jacket 11 covering its lower portion, is preferably provided.-

In event the kettle is to be. used for treatment of a syrup under vacuum, as in carrying outthe process of making candy which is made the subject of my Patent No. 1,101,572, dated June 30,1914, a hood 12 is provided, and the rims 13 and 114 of the kettle and hood are constructed for sealed engagement. Provision is also desirably made forv tilting the kettle 10 upon its sup-A ports, as 15, 16.

As shown, a tubular trunnion 17 is rigidlyV leads laterally out of the trunnion 17, and is connected with the jacket 11. Preferably this pipe is controlled by a valve 20.

' QA tubular bushing 21 is mounted upon the outside wall-of the kettle 10 at the remote side of the kettle from the trunnion 17 and in line therewith. This bushing serves for the attachment to theV kettle of a tubular trunnion 22, which is j ournaled in the ysupport 15. As'shown, the inner-end of the trunnion 22 is :threaded and enters an annular socket 23 formed in the bushing 21.

The nipple 18, bushing 21, and trunnion 22 serve asjournals for a shaft 24, which extendshorizontallyl across the chamber of the kettleand carries a spirally formed pipe coil 25.'` The end portions of the shaft 2,4 are made tubular, as indicated at 26 and 27, and the bores ,of these tubular parts of the shaft communicate with the bore of the pipe coil 25` to form an uninterrupted passage for fluid from one endof the shaft through the coil and thence to a lateral opening 28 adjacent the other end of the shaft.

An annular lflange or bead 29, formed upon the shaft 24 adjacent one end, contacts with the end of the nipple 18, and a collar 30 is fitted about this flange and has threaded engagement with the nipple to provide a means for packing the shaft against leakage ofy fluid about the shaft and into the chamber of the kettle. y

To facilitate the assembling of the parts the shaft 24 is formed in two sections 31, 32, and these sections are united end to end by a threaded nipple 33. An annular bead orL flange 34, formed on the section 32 of the shaft 24 and fitting within the bore of the tubular trunnion 22, serves, in conjunction with the threaded connection of the trunnion 22k and bushing 21, to provide a means,

for packing the shaft against leakage of fluid into the chamber of the kettle through .thebore of the bushing 21.

The pipe coil 25 is rotated, independently of the tilting of the kettle 10, by extending the section 32 of the shaft 24 beyond the outer end of the trunnion 22 andapplying a belt-pulley 35 thereto. To Vprevent leale age of fluid outwardly through the bore of the trunnion 22, the outer end portion of the bore of the trunnion is enlarged to form a threaded socket 36, and a packing gland 37 enters this socket. The bore of the trunnion 22 also has lateral openings 38 and 39, these being preferably formed in line with the lateral Opening` 2S inthe shaft 24. One of these lateral openings, as 38, is connected with the under side of the jacket 11 through a pipe 40. This pipe is desir-ably provided with a pet cock 4l adjacent its lower end a tubular plug 45 enters the outer end of the trunnion 17 about the nipple. A nut 46, applied to the outer end of the nipple 43, serves for clamping a quantity of packing material 47 between the shoulder 44 and thev inner end of the plug 45. If either a heating or a cooling fluid be supplied at the nipple 43, the same may be circulated through the jacket l1 and through the pipe coil 25 while still permitting the pipe coil to be rotated and Without interfering with the tilting of the kettle. If desired the valve 2O may be closed, in which case the iiuid will circulate through the pipe coil 25 alone.

Preferably an intermediate support for the pipe coil 25 'is formed by mounting a spider 48 upon the shaft 24 at about the mid width of thev kettle. The arms of this spider are engaged with one of the intermediate turns of the pipe coil 25.

I claim` as my inventionl. In combination, a tilting jacketed kettle having a tubular trunnion, a'flu'id supply pipe having swiveled connection with the trunnion, and connection between the bore of the trunnion and the chamber of the jacket.

2. In combination, a tilting jacketed kettle having a tubular trunnion, a pipe coil n within the chamber kof the kettle, a fluid supply pipe having swiveled connection with the trunnion, and connections between the bore of the trunnion and the chamber of the jacket and the bore of the trunnion and withinl the chamber of the kettle, a fluid supply pipe having swiveled connection with the trunnion, connections between the bore of the trunnion and the chamber of the jacket and the bore 0f the trunnion and the pipe coil, and a valve controlling one of the last-mentioned connections.

4. In combination, a tilting bowl-shaped kettle having a tubular trunnion, a helical pipe coil horizontally disposed within the kettle and having intermediate turns of greater diameter thanthe turns at either of its ends with an end of the coil axially extended and in swiveled connection with the said tubular trunnion of,r the kettle and means for rotating the coil. I

5. In combination, a tilting bowl-shaped jacketed kettle having a tubular trunnion and connection between the bore of the trunnion and the chamber of the jacket, a helical pipe coil horizontally disposed within the kettle and having intermediate turns of greater diameter than the turns at either of its ends with an venel of the coilaXially extended and in swiveled connection with the said tubular trunnion of the kettle, and means for rotating the coil.

6. In combination, a steam jacketed kettle having trunnions, one thereof being tubular, a steam coil within the chamber of the kettle, a steam inlet having swiveledconnection with the tubular trunnion, and steam passages connecting the bore of the trunnion with the acket of the kettle and with the said steam coil.

f 7. In combination, a steam jacketed kettle having trunnions, one thereof being tubular, a steam coil within the chamber of the kettle, a steam inlet having swiveled connection with the tubular trunnion, steam passages connecting the bore of the trunnion with the jacket of the kettle and with the` said steam coil, and a valve controlling one of said passages. f n
